| Outline of Final Research Achievements |
Total surface bearing (TSB) and patellar tendon bearing (PTB) sockets are widely used for trans-tibial amputees. We used the finite element method to develop a prosthetic model and performed a biomechanical study to assess the impact of level-ground walking, stair ascent and descent and socket configurations on the residual limb by taking into account the load measured in motion analysis. With the TSB socket, contact stress on the stump at the boundary between the socket liner and residual limb was clearly low overall and the fitting was satisfactory compared with the PTB socket. With the PTB socket, contact stress was higher and concentrated in the patellar ligament, on the anterior, medial, and lateral sides of the tibia, and in the popliteal region.
